ARTHUR W. KOON, OF ONARGA, ILLINOIS.

COMBINED k(RAIN'DUIVP AND ELEVATOR.

SPECIFICATION forming part of Letters Patent N0. 715,818, dated December 16, 1902.

Application filed October 31, 1901- Serial No. 80,676. (No model.)

To all whom, it nwty concern.:

Be it known that LARTHUR W.A KOON, a cit-izen of the United States, residing at Onarga, in the county of Iroquois and State of Illinois, have invented a certain new and nseful Combined Grain Dump and Elevator, of which the following is such a full, clear, and exact description as will enable. others skilled in the art to which my invention appertains to make and use the same.

My invention relates to apparatus for dumping grain from a wagon and conveying same to a car, crib, bin, or other suitable receptacle.

The purposes of my invention are to provide means for tipping the front end of a wagon so that the grain contained therein will be discharged on a suitable conveyer, to provide simple and effective means for conveying the grain to the elevator, to provide means for elevating the grain, to provide means to prevent excessive tipping of the wagon, to provide means for gradually lowering the wagon after it has been raised, to provide means adapting the conveyer to be swung away from the Wagon, so as to not interfere with bringing the wagon into position to be tipped, and to provide an extensible elevator of novel and improved construction.

With these ends in View my invention consists in the novel features of construction and combinations of parts shown in the annexed drawings, to which reference is hereby made, and which are hereinafter particularly described, and finally recited in the claims.

Referring to the drawings, Figure l is a top plan of the complete apparatus. Fig. 2 is a vertical transverse section on the line 2 2 of Fig. 1. Fig. 3 is a vertical longitudinal section on the line 3 3 of Fig. l. Fig. 4 is an enlarged end elevation of the left-hand end of the lifting device. Fig. 5 is a vertical transverse section through the elevator and its supporting-standard on the line 5 5 of Fig. 2. Fig. 6 is an enlarged partial front elevation of that part of the mechanism contiguous to the left-hand'end of the platform A2. Fig. 7 is a vertical section on the line 7 7 of Fig. 6, and Fig. S is a partial Vertical section taken on the line of the axis of the shaft A0.

brackets, travel between the posts and prevent binding of the platform against the posts. A shaft A0 is secured on the cross pieces A3. Sheaves A7 are mounted to turn on the shaft A0. A shaft AS, mounted to turn in suitable bearings, extends lengthwise under the platform A2 and carries a miter gear-wheel A0, which meshes with a corresponding miter-wheel B', secured on the main shaft B, which is driven by a horse-power or other suitable motor. A tubular shaft A10 incloses the shaft A8 and has at its ends spools A12, which are secured to and turn with the shaft A10. A clutch member A13 is secured to the shaft A3 and engages with a corresponding member on the tubular shaft A10. Cords A14 are secured to the spools A12, pass around the sheaves A7, and are secured to extensions a on platform A2 in such manner that the winding of the cords on said spools will serve to raise the platform, and the cords will be unwound from the spools as the platform descends.

A lever A15 is fulcrumed on a pin a on one of the posts A and has at its lower extremity a fork d3, which spans the shaftA10 and engages with the spool A12, so that when the lower end of the lever is thrown to the left the fork will act against the spool to move the tube A10 to the left, so as to disengage the clutch A12.

A spring A2o surrounds the sl1aft'A10 and acts against a collar a4 on the shaft to slide the shaft to the right, so as to bring the clutch A13 into engagement when the upper end of the lever A15 is released. The upper end of the lever A15 is shifted to the right by the extension a, engaging with the lower part a2 of the IOO lever A10, and is caught and retained by a spring-latch A10, engaging with the upper end of the lever and serving to hold the clutch out of engagement.

A wheel A17 is secured on the shaft A10. A strap A18 ts around the perimeter of the wheel A17 and is operated by a lever A10, mounted on one of the posts A, so that the strap pressing against the perimeter of the wheel serves as a brake to control the descent of the platform.

In practical use the wagon containing the grain to be dumped is placed with its front wheels resting on a platform A2. The latch A10 is then released, so as to permitthe clutch to come into engagement. The clutch being in engagement, the shaft A10, driven by the shaft B, winds the cords A14 on the spools A12, and thereby raises the platform until the lever A15 is operated to disengage the clutch. A ratchet-wheel A21 on the shaft A10 is engaged by a pawl A22 to prevent premature descent of the platform. When it is desired to lower the platform, the pawl A22 is released and the brake applied so as to cause the platform to descend gradually until it returns to its initial position, when the wagon may be withdrawn and another substituted, and so on as long as the apparatus may continue in operation.

The conveyer mechanism consists of an endless conveyer of the usual well-known form, mounted on a standard in such manner that the conveyer may be swung forwardly or rearwardly, so as not to interfere with placing the wagon in propel' position on the platform A2 and so that when the wagon is in position the conveyer may be swung around to occupy a position under and transverse to the rear end of the wagon.

The standard D is secured on any suitable base D', and its lower part CZ is arched to accommodate a pair of miter-gears, as shown. A tubular shaft D2 is mounted to turn in the standard D aud has a polygonal bore in which a polygonal shaft D2 is slidable. A collar d2 is secured on the shaft D2, and that part of the shaft above the collar is round. A yoke D4 is supported on the collar d2 on the shaft D2, and the yoke turns on the shaft. A miter-gear D0 is secured on the upper end of the shaft D2 and meshes with a similar gear D8 on the shaft D7, mounted to turn in the yoke D4. A roller D10 is secured on a shaft which turns in bearings on the yoke D4. A cogwheel D11 on the shaft of the roller D10 meshes with a similar cog-wheel D9 on the shaft D7. A miter-wheel D13 is secured near the lower extremity of the tubular shaft D3 and meshes with a similar wheel D14, secured on shaft B. Side-boards D15 are supported on the shaft of the rollers D10. An endless belt D12 is carried on the rollers D10. A bail D10 at the free end of the elevator serves as a means for supporting the outer end of the elevator by connecting the bail to any suitable support.

By reason of the construction shown and described the elevator may be raised or lowered or may be swung rearward or forward at pleasure without interfering with the operation of the elevator.

A chute E, supported in any suitable Inanner, receives the grain as it is discharged from the conveyer and carries it into position to be taken up by the elevator.

The elevating mechanism is carried on a rectangular extensible structure supported on the base D'. Tubular corner-posts F are suitably secured to the base and are connected by cross-pieces F2. Rods F are slidable in the corner-posts Fand are connected by cross-pieces F2 and when placed in any desired position may be secured by set-screws f. A bracket F1l1 supports a central upright F4, which is secured immovably and centrally within the lower section of the frame. A similar upright piece F5 is secured at its upper end to a bracket F13 at the upper end of the upper section of the frame and is slidable on the central upright in the lower section of the frame. A rack F0 on the upright F5 meshes with a cog-pinion F7, mounted on a shaft F8 on the upright F4 and provided with a crank F0, by which the shaft may be turned, so as to cause the pinion to operate in the rack in such manner as to raise or lower the upper section of the frame. A ratchet-wheel on shaft F8 is engaged by a pawl f' to prevent backward turniug of the shaft. The upper sprocket-shaft F15 turns in suitable bearings in the bracket F13, and the lower shaft F10 turns in suitable bearings in the lower bracket F14. Sprocket-Wheels F11 carry endless chains F12, to which the elevator-buckets F10 are secured. The shaft F10 carries near its outer extremity a sprocket wheel F17, which is connected by a sprocket-chain F1B with a similar sprocket-wheel B2 on the main drive-shaft B.

The elevator-frame is made extensible in order that it may be used with cribs or bins of different heights. When it is desired to extend the frame, the elevator-chains are unhooked and the crank F9 is then turned to raise the upper section to the desired height. Additional links are then placed in the chain F12 to make them conform to the increased height of the frame. To shorten the frame, this operation would be reversed.

The operation of the apparatus is as follows: The conveyer is rst swung rearward, so that the wagon loaded with grain may pass the conveyer and the wagon may stop with its front wheels resting on the platform A2. The elevator is then swung forward, so as to IOO IIO

lie under and transverse to the rear end of4 the wagon-bed, and the outer end of the elevator is secured in any suitable manner to keep it in the desired position. The mech- 'contained in the Wagon-bed slides out of the bed onto the conveyer and is carried by the couveyer and deposited on the chute, from which it slides into position to be caught and carried upward by the elevator-bucket, from which it is dropped into the bin or other receptacle.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A lifting device for an apparatus of the class described, Consisting of upright posts, a platform slidable between said posts, a shaft rotatable under said platform, a clutch member on said shaft, a tubular shaft inclosing said first-named shaft and having spools and a clutch member, rotatable sheaves at the upper end of said posts, cords secured to spools, passing around said sheaves, and connected with said platform, a lever mounted on one of said posts and adapted to disengage said clutch, means for operating said lever by the upward movement of the platform and a latch engaging with said lever, substantially as set forth.

2. In an apparatus in the class described the combination of a rotatable shaft, a tubular sleeve inclosing said shaft, a clutch member on said shaft, a clutch member on said sleeve, a spring acting to hold said clutch member in engagement, a vertically-movable platform, means for lifting said platform by the rotation of said sleeve, means for retaining said platform in its raised position and means for gradually lowering said platform, as set forth.

In witness whereof I have hereunto subscribed my name, at Onarga, Illinois, this 29th day of July, 1901.

ARTHUR W. KOON.
